CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 639,322, dated December 19, 1899. Application filed May 22, 1899. Serial No. 717,747. (No model.)

To @ZZ whom it may concern.'

Be it known that I, DANIEL WATSON, a citizen of the United States, residing at Argentine, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Car-Roofs, of which the following is a speciiication.

My invent-ion relates to car-roofs; and my object is to produce a car-roof of that type which automatically accommodates itself to the movements of the parts of the car structure, and therebyv is preserved intact, and obviates all chance of leakage through the roof due to the formation of cracks or the opening of seams occasioned by the twisting or rocking of the roof under the various strains to which it is subjected in actual use,'embody ing the features of simplicity, strength, and durability With cheapness of construction.

Vith this object in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described 'and claimed, and in order that it may be understood reference is to be had to the accompanying drawings, in whicl1- g Figure l represents a top plan view of a part of a car-roof embodying my preferred form of construction, Fig. 2 is aside or edge view of the same. Fig. 3 is a transverse section taken on the line III III of Fig. l. Fig. el. is a sectional perspective View of a pair of supercarline-crestings, forming part of my invention. Fig. 5 is a perspective View of a slightly-modified form of the supercarlinecrestings. Fig. 6 is a perspective vview of a modification which embraces changes in the roof-plate construction as Well as in the supercarline crestings used in connection therewith. Fig. 7 is a perspective view of a modified forni of roof-plate. Fig. S is atransverse section of the upper part of the roof, With roof-plates of the type shown in Fig. '7. Fig. 9 is asectional viewtaken longitudinally of t-he car, but transversely of the Supercarlines and roof-plates thereof, said figure illustrating still further modified form of roofplate, whereby crestin gs for the supercarlines maybe dispensed with. Fig. 10 is a similar vieWshoWing a modified form of Supercarlines, roof-plates, and crestings.

Referring now to the drawings in detail, l designates the ,upper longitudinal sills of a car of the usual or any approved construction, and 2 the carlines of the same.

3 and 4. designate longitudinal strips secured upon the carlines of the car.

The construction thus far is common and forms no part of my present invention,eXcept in combination with features which I will now proceed to describe.

5 designates the supercarlines, which are secured upon the strips 8 and 4 and the sills l and are provided in their side edges with semicircular grooves G.

7 designates the roof-plates, preferably of sheet metal, resting upon said strips and sills and fitting snugly between the supercarlines. These plates are provided at their outer ends with the vertically-pendent extensions S, bent upward and outward at their lower ends to provide the cutters 9 to receive the Water flowing down said plates and discharge it at either end externally of the car.

l0 designates the usual side bars, which are secured to the sills l and tensions 8 reliably in position and also provide a bearing for the outer ends of the supercarlines.

The roof-plates at their upper ends in my preferred form of construction are coiled or convoluted, as shown at 1l, and enveloping said coils or convolutions is a ridge-cresting l2, the sides of said cresting being coiled up Witliintlie coils or convolutions ll of the roof-plates in order to provide for a relatively pivotal movement of said parts in a vertical plane, this pivotal connection serving to accommodate any expansive or retractive move ment of the car structure due to heat, cold, forcible contact with other objects, or from any other cause. This' pivotal connection serves to reliably interlock the plates with the ridge-cresting, and thereby prevent independent longitudinal movement (transverse of the car) of the roof-plates and incidentally prevents anyV water getting beneath said plates, and consequently entering the car at this point. The roof-plates are, furthermore, provided with coils or convolutions 14, tting snugly in the semicircular grooves 6 of the supercarlines, this connection serving as an clamp the exa IOO additional means to prevent any independent upward movement of the root-plates.

15 designates the supercarline-crestings These crestings are of length to extend from one edge of the roof to about the opposite side of the rid ge-crestings 12, one set of crestings l5 overlapping the upper or inner ends of the companion or opposing set, as shown most clearly in Figs. 3, 4, and 5. These superearline-crestings, like the roof-plates and ridge-crestings, are by preference ot sheet metal and stamped or otherwise provided at their side margins with the depending inwardly-turned coils or convolutions 16, these coils or convolutions fitting snugly in the coils or convolutions of the roof-plates, and thereby interlocking theroof-plates and supercarline-crestings together and yet premitting a slight pivotal movement, if necessary, to accommodate a movement of the car struc ture.

The outer ends of the supercarlinecrestings between the coils or convolutions thereof are turned upward to provide the shallow gutters 17 to collect the water flowing down the crestings and deflect it to one side or the other upon the roof-plates, and thereby preserve the woodwork of the car as far as possible from contact with the water. The coils or convolutions 16 of said crestings preferably terminate a little outward of the crestings 12, and the plate is stamped or bentfrom such point to form the outwardly-extending ribs or ilanges 19,1esting upon the roof-plates, and the angular extensions 18, the extensions 18 of one set of crestings 15 overlapping the extensions 1S of the opposing set of crestings 15, as shown clearly in the drawings, the vertical portions or arms of said angular extensions fitting against opposite sides of the orestings 12, so as to embrace the same snugly, as shown in Fig. 3. By this arrangement it is apparent that access of water to the supercarlines at points between adjacent or contiguous roof-plates is reliably prevented and that provision for expansion or contraction of the root` is at the same time provided for, as the crestin gs may slide to a limited extent longitudinally from or toward each other, all the while enveloping the contiguous ends of the ridge-crestings. The ribs or Iianges 19 also serve to stiften and strengthen the angularextensions of their respective crestings.

In the preferred form of construction the only provision for preventing the carlinecrestings from rising up from the supercarlines is their iuterlocked connections with the side coils orconvolutions of the roof-plates and the fact that they overlap each other at their inner ends. In the modified form of construction shown in Fig. 5 an additional provision against upward movement of said crestings is made by interlocking the companion supercarline-crestings together. To accomplish this, one of the supercarlinecrestings at its upper or inner end is bent back upon itself, as shown at 20, and the overlapping end of the supercarline-cresting termi# nates in a hook 21, which underlaps the bentback portion 20, this connection serving not only to prevent independent upward movement, but also serving to limit longitudinal movement away from each other, as will be readily understood. Furthermore, to serve as additional means for preventingindependent lateral movement the bent-back portion 2O at its free end, preferably, is provided with a depending arm 22,while diagonally opposite the overlapping portion ot' the companion cresting is provided with an arm 23. The arm 22 bears against one end of the hook 21, while the arm 23 bears against the opposite side of the bent-back portion 20, and also of the integral portion immediately below. This form of cresting is used in connection with the roof-plates shown in Figs. 1 to 3, inclusive.

In the construction thus far described the ridge of the roof is flanked at each side by a coil or convolution of the roof-plates. In Fig. 6 this double coil or convolution construction is dispensed with and the coils or convolutions formed at the upper or inner ends of the roof-plates are interlocked together, as at 24, at the ridge-line or apex of the roof. With this arrangement of the roof-plates the same style of supercarline-crestings may be employed; but I prefer to dispense with the angular extensions 1S and in lieu thereof provide the upper or inner ends of the crestings 15 with coils or convolutions 25, these coils or convolutions being pivotally interlocked together and to the interlocked coils or convolutions 11 of the roof-plates. In other respects the construction of the parts is precisely the same.

In Fig. 8 the roof structure is provided with the usual ridge-pole 26, provided with longi= tudinal grooves 27 in its under side edges. In this connection I by preference provide the roof'plates with the side coils or convolutions 14 for engagement, as described,with the semi= circular grooves 6 ot' the supercarlines, (see Fig. 2,) and .in addition and in lieu of the coils or convolutions 11 at their upper ends with the extensions 28, formed with marginal upturned beads 29, said beaded extensions 2S projecting into the grooves 27 of the ridge-k pole. (See Fig. 8.) With this construction. the ridge-crestings may be dispensed with. Either style of supercarline-cresting shown in Figs. 4 or 5 may be employed in connection with this type of roof-plate.

In Fig. 9 is illustrated a still further modified form of roof-plate 7. In this connection the coils or convolutions 14-rb at the sides of the roof-plates are of semicircular form in crosssection and terminate in'vertical iianges 30, projecting upward and engaging grooves 31 in the supercarlines. This style of roof-plate may be used with the supercarline-crestings, if desired, may terminate in ridge-coils 11, if desired, to be enveloped in the ridge-crestings, or may terminate in a beaded extension, as shown in Figs. 7 and 8, and engage grooves IOC in opposite edges of the ridge-pole. If no ridge-pole is employed,they will by preference be formed with ridge-coils at their upper ends.

In Fig. l() atruncated supercarline is shown, so as to leave the grooves 6a, corresponding to grooves 6 in its side edges,'in quadrant instead of semicircular form. With this style of supercarline a supercarline-cresting 15a is employed, this cresting being formed at its opposite side margins with the coils or convolutions 16a, corresponding to coils or convolutions 16. As these coils or convolutions 16a are oppositely disposed to the coils or convolutions 16, it is necessary that the engaging coils or convolutions 14a of the roof-plates 7 be also coiled in the opposite direction, that they may pivotally interlock with the coils or convolutions 16a. With this style of .construction the same conditions obtain as with the preceding figure-that is to say, the roofplates may terminate in ridge-coils to be enveloped by ridge-crestings or may be provided with beaded extensions to engage grooves in the side edges of the ridge-pole.

From the above description it Will be apparent that I have produced a car-roof which embodies the features of advantage enumerated in the statement of invention and which is susceptible of various changes in the detail construction, form, arrangement, or proportions of the parts without departing from the spirit and scope or sacrificing any of the advantages of the invention.
